Help with Structures/Blocks

[Odb718]

I need help with the blocks that make structures.  In Tourain I was messing around with new structures in Editroid. I was coming up with an idea. I made a block, that uses 1 8x8 tile as all 4 in the block, use 4 different tiles. How can I get it so that block uses only that one tile for all four spots again???

No I dont have a back up. Plus I'd like to learn how to do this so I can use maybe 2x tiles for one block instead of having all 4 in a row. Do I have to hex edit it? Can Editroid do this??

Sorry. Just found out on Editroid. You hold Shift and click the tiles into place.
My bad.
